Abstract (en)
[origin: EP2884374A1] A disclosed display device includes a touch panel including s number of receiving electrodes and k number of driving electrodes which are formed to intersect the receiving electrodes, k being less than s and larger than 2, the touch panel provided in an in-cell type. The display device further includes a touch sensing unit configured to respectively supply a first driving voltage and a second driving voltage to an nth driving electrode and an (n+1)th driving electrode, which are adjacent to each other among the driving electrodes, to determine whether the nth driving electrode is touched, n being a natural number which is more than one and less than k, the touch sensing unit further configured to respectively supply the first driving voltage and the second driving voltage to a kth driving electrode and a (k-1)th driving electrode to determine whether the kth driving electrode is touched.
